Blood Tests for Heart Damage and Disease

Troponin and CK-MB Tests for Heart Attacks:

* Elevated blood levels of troponin indicate muscle damage, especially in the heart.
* Troponin I: Reference range: 0 - 0.04 ng/mL
* Troponin T: Reference range: 0 - 0.01 ng/mL
* High blood levels of CK-MB indicate a potential heart attack.
* CK-MB reference range: 3-5% of total CK or 5-25 IU/L

Enzymes in Blood Enzyme Testing:

* Enzymes regulate chemical reactions in the body.
* CK-MB is an enzyme released into the blood when cardiac muscle is damaged.

Risk Prediction:

* Troponin tests can predict heart disease risk in both people with and without diabetes.

Hormones and Blood Tests:

DHEA:

* Known as the "antiaging hormone," DHEA levels decline with age.
* Low DHEA may impact body functions such as erectile function, immune function, and bone density.

Hemoglobin A1C:

* Measures blood sugar control over the past 2-3 months.
* Not affected by daily glucose fluctuations, making it a crucial test for diabetics.
* Recommended every 3-6 months by the American Diabetes Association.
